The only "Jewish Senator" I can think of on the GOP ticket is Norm Coleman. McCain/Coleman would be tolerable. The other Jewish Senators are all socialists. And the ultra-liberal pro-abortion, gun-grabbing, illegal alien loving Joe LIEberman stood by side-by-side with Al Gore when then conspired to throw out of the overseas millitary votes. I wouldn't want him for dog catcher, let alone Vice President.
There is Arlen Spector but he is too sick, too old, and too liberal.
